kuivapuristus

Kuivapuristus, meaning "dry pressing" in Finnish, is a method of manufacturing ceramic tiles. In this process, a ceramic powder, mixed with a small amount of moisture, is pressed into a mold under high pressure. The pressure compacts the powder into a dense, solid form. This dry pressing technique is widely used for producing floor and wall tiles due to its efficiency and ability to create tiles with precise dimensions and sharp edges. The moisture content is critical; too much would prevent proper compaction, while too little could lead to dusting. After pressing, the tiles are dried further and then fired in a kiln at high temperatures to achieve their final hardness and durability. This method contrasts with traditional wet pressing, where a more fluid clay mixture is used. Kuivapuristus allows for a high volume of production and is a cornerstone of modern ceramic tile manufacturing, enabling the creation of a vast array of tile types, sizes, and finishes.
